简述：

用一下面向对象方法，用Python写一下链表

代码：

List.py

class Node:
	next = None
	data = None
	def __init__(self,nodeData):
		self.data = nodeData

class List:
	root = None
	size = 0;
	def __init__(self,newRoot):
		self.root = newRoot
	def __init__(self):
		self.root = None
		size = 0
		
    #delete node from root
	def __del__(self):
		if self.root is None:
			return
		curNode = self.root
		while curNode.next is not None:
			tempNode = curNode
			curNode = curNode.next
			tempNode = None
		curNode = None
  
	#Insert a new node to the list
	def Insert(self,newData):
		newNode = Node(newData)
		if self.root is None:
			self.root = newNode
			return
		tempNode = self.root
		while tempNode.next is not None:
			tempNode = tempNode.next
		tempNode.next = newNode
		self.size += 1
		
	#def Get data of Position pos
	def GetData(self,pos):
		if pos >= self.size or pos < 0:
			return None
		else:
			tempNode = self.root
			for i in range(0,pos):
				tempNode = tempNode.next
			return tempNode.data
	
	#Remove a certain node
	def Remove(self,theData):
		curNode = self.root
		if curNode is None:
			return
		if self.size == 1 and curNode.data == theData:
			curNode.data = None
			curNode = None
			self.size -= 1
			return
		while curNode.next is not None:
			if curNode.next.data == theData:
				tempNode = curNode.next
				curNode.next = curNode.next.next
				tempNode = None  #remove the node,but curNode stays still
				self.size -= 1
			else:
				curNode = curNode.next
				
	#Get Root Node
	def GetRoot(self):
		return self.root
		
	#def Get Size
	def GetSize(self):
		return self.size
	
	#print the data of the list
	def Print(self):
		tempNode = self.root
		while tempNode is not None:
			print (tempNode.data)
			tempNode = tempNode.next	  
	

	    
    

test.py

# coding=gbk
import List

def main():
    print ("start main()")
    mylist = List.List()
    for i in range(0,10):
        mylist.Insert(i)
    print ('输出该单链表：\n')
    mylist.Print()
    print ("\nmylist的size：", mylist.GetSize())
    print ("\n删除1号索引的元素：")
    mylist.Remove(1)
    print ("输出删除1号索引后链表的元素：\n")
    mylist.Print()
    print ("\n删除后的元素个数：%s" % mylist.GetSize())

main()
    

可以用eclipse python插件执行

或者用python main.py执行在linux上

输出：
